Manage user attributes
Fetch the current user's attributes
Invoke the following api to get the list of attributes assigned to the user.
func fetchAttributes() { Amplify.Auth.fetchUserAttributes() { result in switch result { case .success(let attributes): print("User attributes - \(attributes)") case .failure(let error): print("Fetching user attributes failed with error \(error)") } }}
func fetchAttributes() -> AnyCancellable { Amplify.Auth.fetchUserAttributes() .resultPublisher .sink { if case let .failure(authError) = $0 { print("Fetch user attributes failed with error \(authError)") } } receiveValue: { attributes in print("User attributes - \(attributes)") }}
Update user attribute
Invoke the update api for creating new or updating existing user attributes.
func updateAttribute() { Amplify.Auth.update(userAttribute: AuthUserAttribute(.phoneNumber, value: "+2223334444")) { result in do { let updateResult = try result.get() switch updateResult.nextStep { case .confirmAttributeWithCode(let deliveryDetails, let info): print("Confirm the attribute with details send to - \(deliveryDetails) \(info)") case .done: print("Update completed") } } catch { print("Update attribute failed with error \(error)") } }}
func updateAttribute() -> AnyCancellable { Amplify.Auth.update(userAttribute: AuthUserAttribute(.phoneNumber, value: "+2223334444")) .resultPublisher .sink { if case let .failure(authError) = $0 { print("Update attribute failed with error \(authError)") } } receiveValue: { updateResult in switch updateResult.nextStep { case .confirmAttributeWithCode(let deliveryDetails, let info): print("Confirm the attribute with details send to - \(deliveryDetails) \(info)") case .done: print("Update completed") } }}
Verify user attribute
Some attributes require confirmation for the attribute update to complete. If the attribute need to be confirmed, the result of the above api will be CONFIRM_ATTRIBUTE_WITH_CODE
. A confirmation code will be sent to the delivery medium mentioned in the delivery details. When the user gets the confirmation code, you can present a UI to the user to enter the code and invoke the confirm attribute api with their input:
func confirmAttribute() { Amplify.Auth.confirm(userAttribute: .email, confirmationCode: "390739") { result in switch result { case .success: print("Attribute verified") case .failure(let error): print("Update attribute failed with error \(error)") } }}
func confirmAttribute() -> AnyCancellable { Amplify.Auth.confirm(userAttribute: .email, confirmationCode: "390739") .resultPublisher .sink { if case let .failure(authError) = $0 { print("Update attribute failed with error \(authError)") } } receiveValue: { _ in print("Attribute verified") }}
Send user attribute verification code
If an attribute needs to be verified while the user is authenticated, invoke the api as shown below:
func resendCode() { Amplify.Auth.resendConfirmationCode(for: .email) { result in switch result { case .success(let deliveryDetails): print("Resend code send to - \(deliveryDetails)") case .failure(let error): print("Resend code failed with error \(error)") } }}
func resendCode() -> AnyCancellable { Amplify.Auth.resendConfirmationCode(for: .email) .resultPublisher .sink { if case let .failure(authError) = $0 { print("Resend code failed with error \(authError)") } } receiveValue: { deliveryDetails in print("Resend code sent to - \(deliveryDetails)") }}
